The Panthers continue to show serious interest in Islanders’ goaltender Felix Potvin, The Post has learned.

With Panthers No. 1 goalie Trevor Kidd out for at least two months — possibly longer — with a dislocated shoulder, Florida is stuck for the time being with backup Mikhail Shtalenkov. In trading for Potvin, the Panthers would likely give the Isles a package that includes Shtalenkov, who would back up rookie Roberto Luongo. The NHL, however, prohibits any trades between Dec. 19 through the 27th.

Panthers GM Bryan Murray was in Toronto Wednesday and attended the Isles-Maple Leafs game. Potvin started the game and allowed all five goals in Toronto’s 5-1 victory. Potvin, who earns a team-high $2.7 million this season, has lost six consecutive starts.

RW Mariusz Czerkawski, who leads the Isles with 12 goals, will be out a week with a strain to his right side of his upper torso.

The Isles have demoted RW Mark Lawrence to Chicago of the IHL. Lawrence has no goals in 21 games. The team has called up from Chicago LW Niklas Andersson, RW Scott Pearson and D Dallas Eakins.

Isles pro scout Kenny Morrow will be joining the coaching staff for about one week each month to work with the defensemen.
